Abstract
A heat pump design with an economizer flash tank provides an efficient way to operate the system in both heating and cooling modes. Various expansion device types can be employed with this design. The invention enhances system performance in both cooling and heating modes of operation, through utilization of the flash tank economizer cycle, in simplistic and cost effective manner, while sustaining expansion device and entire system functionality through an appropriate refrigerant rerouting around the compressor and the flash tank.
